Now I create a system that can delete multiple data using select option. But here I got some issues. When i only select one data, and press button delete, it will delete. But if I choose more than one data, for example, 3 data, it will only delete the latest id of the data. Below is my the image
And below is my code:
index.php
<form method="post" id="multiple_select_form">
<select name="framework" id="framework" class="form-control selectpicker" data-live-search="true" multiple>
<?php foreach ($results as $row2): ?>
<option value= <?php echo $row2["framework_id"]; ?>><?php echo $row2["framework_name"];?></option>
<?php endforeach ?>
</select>
<br /><br />
<input type="hidden" name="framework_id" id="framework_id" />
<input type="submit" name="submit" class="btn btn-info" value="Submit" />
</form>
<script>
$(document).ready(function(){
$('.selectpicker').selectpicker();
$('#framework').change(function(){
$('#framework_id').val($('#framework').val());
});
$('#multiple_select_form').on('submit', function(event){
event.preventDefault();
if($('#framework').val() != '')
{
var form_data = $(this).serialize();
$.ajax({
url:"insert.php",
method:"POST",
data:form_data,
success:function(data)
{
//console.log(data);
$('#framework_id').val('');
$('.selectpicker').selectpicker('val', '');
alert(data);
}
})
}
else
{
alert("Please select framework");
return false;
}
});
});
</script>
insert.php
<?php
include("configPDO.php");
$smt = $conn->prepare("DELETE FROM frame_list WHERE framework_id = '".$_POST["framework_id"]."'");
$smt->execute();
if($smt){
echo "Data DELETED";
}else{
echo "Error";
}
?>
Can anyone knows how to solve this problem? Thanks
framework
will hold one value every time.
Use input arrays -
Change name="framework"
to name="framework[]"
.
and in query -
WHERE framework_id in ('". implode("','", $_POST["framework_id"]) ."')"
Try to use parameter binding for security.
